- Kline (Ramsey and Kollonitsch, 1977), except for "other," which
was based on judgment. The Kline report lists three additional
manufactuers (USS Agrichemicals, Occidental, Swift) ($3 million
total sales) but does not identify their products or active ingredients.
We assumed that their active ingredients were similar in identity
and proportion of sales to those listed here, and we do not list
them on the table or include them in the calculations.
- Allocation of each manufacturer's sales to major products was based
on judgment.
- Sales for each active ingredient are set equal to the sales for
the product containing that active ingredient. Exception: For Ortho
Weed-B-Gone, MCPP and silvex (fenoprop) are each set at $2.5 million
rather than $7.5 million because only one-third of Ortho Weed-B-Gone
products contained these active ingredients.
- Eliminating duplicates.
- Combining active ingredient sales across all products in which
it appears.
- Sales for each active ingredient divided by total sales ($20.4
million).
